When I select the cycle (normal, heavy) and then click the start button nothing happens. The lights are on on the control panel. I checked all power connections including the one under the kick plate. Power doesn't seem to be the issue. I also checked the continuity for the thermal fuse and it seems to be okay. The door latch appears to be working okay in that the switch is being pushed down and I also tested the continuity of the switch. I'm not sure what could be wrong. I've heard of a reset sequence but I am not sure if that applies to this model also.

The door switch will have to be closed when you make this test. You can open the control panel so you can work on it while having then inner door panel closed so the door switch is latched. Circuit will be hot at that point and you can measure voltages.

Okay. So the thermal fuse has continuity. The door switch seems to be working. No power issues. I checked the float to make sure it wasn't sticking. It seems to be working okay. Any suggestions on what the problem is or what else I should check to diagnose the problem?

I suspect you are dealing with a bad touch panel. You can use the tech sheet that Reg linked you to an check the continuity of the keypads. You can also measure for voltage going from the control board to the touchpad, it's some low voltage DC, I think in the range of 5 to 12 V DC.

If it turns out that the touchpad is bad, you can buy a new one from the link below.

It ended up not being the touchpad. It ended up being the circuit board. Now I am having trouble with the top rack not cleaning. I don't think it is spraying. Is it possible I hooked something up wrong?
